Elasticsearch常见启动报错以及解决方法

      1. Elasticsearch启动报错解决方法

1、机器内剩余内存较少,会启动失败,并且有类似如下报错:

Java HotSpot(TM) 64-Bit Server VM warning:INFO: os::commit_memory(0x000000008a660000, 1973026816, 0) failed; error='Cannot allocate memory' (errno=12)

这是因为es的jvm参数-Xmx和-Xms默认都为2G

修改config下的jvm.option文件

# vi elasticsearch/elasticsearch-6.1.0/config/jvm.opstions

-Xms2g

-Xmx2g

改为

-Xms1g

-Xmx1g

或更小

-Xms512M

-Xmx512M

再次启动即可

2、启动的时候出现:

1、ERROR: bootstrap checks failed system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk...

解决方法:在elasticsearch.yml中配置bootstrap.system_call_filter为false,注意要在Memory下面:

bootstrap.memory_lock: false

bootstrap.system_call_filter: false

3、ERROR: bootstrap checks failed max file descriptors [4096] for elasticsearch process likely too low, increase to at least [65536] max number of threads [1024] for user [lishang] likely too low, increase to at least [2048]

解决方法:切换到root用户,编辑limits.conf 添加类似如下内容

#vi /etc/security/limits.conf

添加如下内容:

* soft nofile 65536

* hard nofile 131072

* soft nproc 2048

* hard nproc 4096

 

4、max number of threads [1024] for user [lish] likely too low, increase to at least [2048]

解决方法:切换到root用户,进入limits.d目录下修改配置文件。

#vi /etc/security/limits.d/90-nproc.conf

修改如下内容:

* soft nproc 1024

修改为

* soft nproc 2048

5、max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144]

解决方法:切换到root用户修改配置sysctl.conf

#vi /etc/sysctl.conf

添加下面配置:

vm.max_map_count=655360

并执行命令:

#sysctl -p

然后,再启动elasticsearch,即可启动成功。

 

 

报错[seci-*****] creating index,cause[api],templates[],shards[5]/[1],mappings[]

[seci-*****/********]create_create_mapping

解决方法:

#vi /etc/security/limits.conf

* soft nofile 65536

* hard nofile 131072

这个文件的最后两行,把上面这个配置覆盖了。删掉最后两行即可
